Product Description
The RF2915 is a monolithic integrated circuit intended for use as a low cost FM transceiver. The device is provided in 32-lead plastic TQFP packaging and is designed to be used with a PLL IC to provide a fully functional FM transceiver. The chip is intended for digital (ASK, FSK, OOK) applications in the North American 915MHz ISM band and European 433MHz/868MHz ISM band. The integrated VCO has a buffered output to feed the RF signal back to the PLL IC to form the frequency synthesizer. Internal decoding of the RX ENABL and TX ENABL lines allow for half-duplex operation as well as turning on the VCO to give the synthesizer time to settle and complete power down mode.
